The pipe defect detecting apparatus 1 provided by the present invention is described below with reference to fig. 1 to 2.
The internal structure defects of the drainage pipeline are the key points concerned by water engineering, the internal structure defects of the pipeline are generally evaluated by acquiring a pipe wall image in an optical shooting mode, and common instruments comprise a pipeline robot, a pipeline periscope and the like. However, this method is difficult to be applied to the situation that the pipeline is full of water, and pipeline precipitation and dredging are required. Although pipeline sonar is suitable for full-pipe conditions, it can only assess functional deficiencies. Some high water level pipelines are difficult to adopt plugging and precipitation measures due to large pipe diameter and high flow velocity, thereby causing serious influence on engineering construction.
To solve the problems in the prior art, the present invention provides a pipe defect detecting apparatus 1, comprising: the mounting part 2 is provided with a mounting cavity 6, a first opening 7 communicated with the mounting cavity 6 is formed in the mounting part 2, and the first opening 7 is used for being arranged towards a pipe cavity of the pipeline to be tested; the detection device 3 comprises an air bag 11 and a camera device 12, the air bag 11 is movably arranged in the installation cavity 6, the air bag 11 is arranged in a sealing mode, and the camera device 12 is arranged in the air bag 11; the inflating device 4 is communicated with the air bag 11 and is used for inflating the air bag 11, so that the size of the air bag 11 can be adjusted; and the driving device 5 comprises a traction piece 17 and an ejection mechanism 18, the traction piece 17 is arranged on the air bag 11, and the ejection mechanism 18 is in driving connection with the traction piece 17 so as to eject the traction piece 17 out of the first opening 7.
It should be noted that the mounting member 2 mainly plays a bearing role or a guiding role, and at the beginning of the detection, the mounting member 2 can be placed at one end of the pipe to be detected, so that the first opening 7 faces the pipe equipment to be detected. The pulling element 17 is then ejected out of the first opening 7 by the ejection mechanism 18, so that the pulling element 17 can pass through the pipe to be tested. In order to facilitate use, a catching net is generally placed at the outlet end of the pipeline to be tested, and the traction piece 17 is recovered through the catching net, so that an operator can drive the air bag 11 to penetrate through the first opening 7 to enter the pipeline to be tested through the traction piece 17 at the other end of the pipeline to be tested.
It should be noted that, in the process of the airbag 11 passing through the pipeline to be measured, the airbag 11 needs to be inflated, so that the surface of the airbag 11 is close to the pipe wall, and if water flows exist in the pipeline to be measured, the airbag 11 is blocked by the water flows and is subjected to large water pressure, so that the airbag can move downstream under the action of the pressure to drive the camera device 12 to move forward, and image acquisition of the pipeline wall is performed. If the pipeline to be detected is subjected to extrusion deformation, the air bag 11 can be deflated to reduce the size of the pipeline to be detected, so that the air bag 11 can easily pass through the deformed pipeline to be detected. Compared with the pipeline detection device 3 in the prior art, the pipeline defect detection equipment 1 provided by the invention can adapt to the internal working condition of a complex pipeline, and can achieve a good adaptation effect no matter the pipeline to be detected is low-water level or high-water level; the air pressure of the air bag 11 is adjusted, so that the air bag 11 can smoothly pass through a pipeline with serious deformation; in addition, because the camera device 12 is arranged in the air bag 11, the air bag 11 is transparent, the influence of the turbidity of water on optical shooting can be reduced, and the camera device still has good adaptability to sewage environment.
Specifically, referring to fig. 1-2, the pulling member 17 includes a pulling rope 19 disposed at an end of the air bag 11 near the first opening 7, and a pulling block 20 disposed at an end of the pulling rope 19, and the ejection mechanism 18 is drivingly connected to the pulling block 20. It should be noted that the length of the pulling rope 19 is generally several times of the length of the pipe to be tested, and after the ejection mechanism 18 ejects the pulling block 20 at one end of the pipe to be tested, the ejected pulling block 20 can be caught by arranging the catching net at the other end of the pipe to be tested. Because the air bag 11 is not inflated in the initial stage, a user can pull the air bag 11 to enter the pipeline to be detected through the first opening 7 by picking up the traction block 20, and at the moment, the air bag 11 is inflated, so that the defect detection of the pipeline to be detected can be carried out.
It should be noted that the shape and material of the traction block 20 are not limited in the present invention, and are preferably a material with corrosion resistance and large density, and the volume is not too large, specifically, referring to fig. 1-2, in the embodiment provided by the present invention, the traction element is a sphere, and may be a small metal sphere or a stone sphere, etc. with good fluid stability; the traction piece can be designed into other shapes, such as an umbrella shape, the umbrella-shaped traction piece is preferably arranged elastically, is extruded by the inner wall of the mounting piece to be in a tightening state when not ejected, and is in an opening state when being ejected out of the first opening, and the umbrella-shaped traction piece can ensure a relatively stable movement direction, so that the traction piece can stably move along the length direction of the pipeline to be tested and is captured by the capture net, and the effective test is ensured; in addition, the pulling rope 19 may be made of a material having high toughness, such as a wire rope or a nylon rope.
Note that, in order to facilitate the observation of the specific structure, the airbag 11 and the like are not inserted into the mounting member 2 in the drawings of the present invention, which are merely schematic in structure and do not illustrate the final mounting state.
The ejection mechanism 18 primarily powers the drag block 20 such that the drag block 20 can eject the first opening 7. Further, in the technical scheme provided by the invention, the ejection mechanism 18 comprises an air storage part 21 arranged in the installation cavity 6, the air storage part 21 is communicated with the inflation device 4, a pressure limiting valve 22 is arranged at the position of the air storage part 21 facing the first opening 7, and the traction block 20 is arranged at the position of the pressure limiting valve 22. It should be noted that the gas storage part 21 is mainly used for storing high-pressure gas, when the high-pressure gas reaches the pressure limited by the pressure limiting valve 22, the pressure limiting valve 22 is opened, and the high-pressure gas is jetted and impacts the traction block 20 to provide power for the traction block 20, so that the traction block 20 can be ejected out of the first opening 7. If the pressure limiting valve 22 is arranged at a lower position and is close to the bottom wall of the installation cavity 6, the traction block 20 can be placed on the bottom wall of the installation cavity 6 in a position corresponding to the pressure limiting valve 22, and high-pressure gas blown out by the pressure limiting valve 22 can be blown onto the traction piece 17; if the pressure-limiting valve 22 is arranged at a higher position, a high tray can be arranged in the installation cavity 6, and the traction piece 17 is placed on the tray and arranged corresponding to the position of the pressure-limiting valve 22, which is not limited in the invention. It should be noted that the inflator 4 can provide high pressure gas and low pressure gas simultaneously, the airbag 11 is filled with low pressure gas, and the inflator 4 is communicated with the airbag 11 and the gas storage member 21 through a pipeline to fill the two devices with gas respectively.
As mentioned above, the air bag 11 needs to be inflated, so that the surface of the air bag 11 is attached to the pipe wall of the pipe to be measured, and thus the air bag 11 moves toward the downstream direction of the pipe under the thrust of the upstream water. Generally, the inner pipe wall of the pipeline to be measured is very rough, and in order to prevent the airbag 11 from being broken due to overlarge friction force between the airbag 11 and the pipe wall, in the technical scheme provided by the invention, two ends of the airbag 11 in the length direction are respectively sleeved with a protective gasket 13. After the air bag 11 is filled with air, the protective gasket 13 will contact with the inner pipe wall of the pipe to be tested, so as to provide a certain protection effect for the air bag 11.
Further, during the movement of the air bag 11, there may be a case where the air bag 11 cannot pass through the pipe to be measured because the friction is too large or the water flow is too small. Although the effect of adjusting the volume of the airbag 11 can be achieved by adjusting the gas inside the airbag 11, the inflation and deflation amount of the gas is not easy to control because the airbag 11 itself is invisible; if the pulling of the pulling rope 19 is performed, the air bag 11 may be damaged by friction. Therefore, in the technical scheme provided by the invention, the middle part of the air bag 11 is inwards sunken to form a sunken area 14, the sunken area 14 is arranged between the two protective gaskets 13, and the inner diameter of the air bag 11 in the sunken area 14 is smaller than the inner diameter of the air bag 11 at two ends. By looking sideways at the airbag 11, the depressed area 14 of the airbag 11 presents a saddle shape, and the depressed area 14 can reduce friction between the airbag 11 and the inner pipe wall of the pipeline to be tested, so that the airbag 11 can easily pass through the pipeline to be tested.
Because the camera device 12 needs to observe the internal environment of the pipeline to be measured, the camera device 12 includes a panoramic camera and an illuminating lamp disposed on the panoramic camera, and the illuminating lamp is electrically connected with the panoramic camera. The panoramic camera can capture the pipe body condition in the pipeline to be tested at 360 degrees; because comparatively dark in the pipeline that awaits measuring, the light mainly plays the effect of illumination, can help the panorama camera to observe the environment in the pipeline that awaits measuring. Of course, a camera with an illumination function or a camera with a night vision function may also be selected, and the above implementation effect may also be achieved, which is not limited in the present invention.
It should be noted that, in the technical solution provided by the present invention, an accommodating cavity 15 is provided in the airbag 11, the accommodating cavity 15 is provided corresponding to the recessed area 14, and the accommodating cavity 15 is provided in isolation from the cavity of the airbag 11, and the image pickup apparatus 12 is provided in the accommodating cavity 15. It can be understood that the camera device 12 is arranged in the recessed area 14, and does not extrude with the pipe wall of the pipe to be measured, so as to protect the camera device 12; the accommodating cavity 15 is isolated from the cavity of the air bag 11, so that the inflation and deflation of the air bag 11 are prevented from influencing the operation of the camera device 12.
Further, gasbag 11 still includes the extension pipe 16 of locating gasbag 11 one end far away from first opening 7, and extension pipe 16 has the lumen, and the lumen of extension pipe 16 with hold chamber 15 intercommunication, the cable of panoramic camera is worn to locate in the lumen. The receiving cavity 15 may be sealed and exist as a separate space inside the airbag 11, but in this case, the camera needs to be in communication connection with the ground equipment in a wireless mode. Because the environment is complicated under water, generally wired camera measuring accuracy and signal transmission speed all can be better, consequently set up extension pipe 16, panoramic camera's cable can be connected to the equipment on ground through extension pipe 16 for panoramic camera and cable can be isolated in water, protect panoramic camera.
Because the environment of the pipeline to be detected is various, some pipelines to be detected have certain depth from the ground or the monitoring surface, and the detection equipment is not conveniently placed at the moment. Therefore, in the technical scheme provided by the invention, the mounting part 2 comprises a vertical section 8 and a horizontal section 9 which are arranged in a mutually bent mode, the vertical section 8 and the horizontal section 9 are provided with a communicated mounting cavity 6, and the horizontal section 9 is used for extending into a pipeline to be tested; the first opening 7 is arranged on the horizontal section 9, the ejection mechanism 18 is arranged on the horizontal section 9, and the end, far away from the horizontal section 9, of the vertical section 8 is provided with a second opening 10 communicated with the installation cavity 6.
At the initial stage that detects, can be in the vertical section 8 of the handheld installed part 2 of detection well head, put into the pipeline that awaits measuring with the horizontal segment 9 of installed part 2, at the in-process of placing, because the bending type is formed with the bent angle between horizontal segment 9 and the vertical section 8, can use horizontal segment 9 to catch the pipe wall of the pipeline that awaits measuring, fix a position the pipeline that awaits measuring. Because some pipelines to be detected are deeper than the detection wellhead, in the technical scheme provided by the invention, the vertical section 8 comprises a plurality of pipelines which are sequentially sleeved, and the pipelines are mutually connected in a sliding manner, so that the length of the vertical section 8 can be adjusted, and the pipelines to be detected with different depths can be matched by adjusting the length of the vertical section 8.
The working flow of the pipeline defect detection equipment 1 provided by the invention is roughly as follows:
1. installing and connecting equipment;
2. placing the mounting member 2 at the bottom of the inspection well so that the first opening 7 is arranged towards the pipeline to be tested;
